• 先行词是the way,place,time,reason关系副、代词何时可省?为什么这句要加where:We've all used thermometers to measure temperature but sometimes we need to measure temperature in places WHERE you can't put a thermometer.语法说,先行词是the way,表示方式,可用that（可省）或in which来引导一个定语从句.如果先行词是时 间或原因,也可用that（可省）或when或why来引导定语从句.如：（1）This was the reason that/why he was late yesterday.（2）This is the last time that I shall give you a lesson.这句是道改错题,还要加上where 是什么原因?没表达清楚，我的意思是that代替关系副词，那么我这道改错题为何还要加
